Should be a municpal dumb site taking the stumps. They stockpile them and tubgrind them. Every clean up job I've been at had this in some form. You cant deal with them at a storm level with a stump grinder.

I dig them out and remove most of the dirt and rocks from the stump , so it doesen't damage tub grinders . Depending on where I dump them they have been charging anywhere from 35$ to 100$ for a s/a dump truck load. One place was charging 100$ per stump. This is one I dug up and replanted.
